I'm not sure what i can expect from the touch sensor, so i would ask other community members about their experiences with the sensor. What is the biggest distance from a sensor field and a finger to recognize a "touch". Is it possible to mount an OLED display in front of the sensor field?</P><P></P><P>Best Mario</P></BODY></HTML> Mon, 25 Mar 2013 07:22:48 GMT mariod 2013-03-25T07:22:48Z Expectations to MPR121 https://community.nxp.com/t5/Sensors/Expectations-to-MPR121/m-p/238994#M293 <HTML><HEAD></HEAD><BODY><P>Hi everyone,</P><P></P><P>i've played around with a MPR121 Touch Sensor.
